Adverse Drug Reaction Reduction

1. A method for using a server to generate an advisory message to a user, comprising: receiving, by the server, a first list, said first list including medications currently being taken by a patient; generating, by the server, a first code, said first code representing said first list of medications currently being taken by the patient, but not disclosing an identification of individual elements of said list; sending by the server said code; thereafter: receiving, by the server, from the user: said first code, and an identification of at least one additional medication proposed to be taken by the patient; determining, by the server, whether an adverse drug reaction warning should be generated, the adverse drug reaction warning indicating a potential danger of concurrent administration to the patient of: (a) at least one medication from said list of medications currently being taken by the patient and (b) the additional medication proposed to be taken by the patient; sending the adverse drug reaction warning, by the server, in response to determining that The adverse drug reaction warning should be generated; generating, by the server, a second code, said second code being different from said first code, and said second code representing a second list, said second list including the medications currently being taken by the patient and the additional medication proposed to be taken by the patient, but said second code not disclosing an identification of individual elements of said second list; and sending said second code to the user from the server.

2. The method according to claim 1 , wherein sending the first code to the user comprises determining whether a code already exists with respect to the first list, and, if so, sending the already-existing code to the user, and, if not, generating the first code and sending the generated first code to the user.

3. The method according to claim 1 , wherein generating the first code comprises generating the code not responsively to a pharmaceutical characteristic of at least one of the current medications.

4. The method according to claim 1 , wherein receiving the first list from the user comprises receiving an indication of a dosage of at least one of the medications currently being taken by the patient, wherein sending the first code comprises sending the first code responsively to the first list and the dosage, and wherein determining, by the server, whether an adverse drug reaction warning should be generated, comprises determining whether the adverse drug reaction warning should be generated based on the first list, the additional medication, and the dosage.

5. The method according to claim 4 , wherein sending the first code responsively to the received indication of the dosage comprises: if the dosage is near a dosage of the one of the medications currently being taken by the patient for which a code has already been generated, sending as the first code the same code that has already been generated; and if the dosage is not near a dosage of the one of the medications currently being taken by the patient for which a code has already been generated, sending as the first code a code different from the code that has already been generated.

6. An adverse drug reaction control system for generating an adverse drug reaction warning to a user, comprising: a computer including drug-input functionality that receives a first list, said first list including medications currently being taken by a patient; a code generator that generates a first code, said first code representing said first list of medications currently being taken by the patient, but not disclosing an identification of individual elements of said list; code-output functionality; and adverse drug reaction warning generation functionality, the drug-input functionality receiving from a user, following generation of the code, the first code and an identification of at least one additional medication proposed to be taken by the patient; the adverse drug reaction warning generation functionality: determining whether to generate an adverse drug reaction warning indicating a potential danger of concurrent administration to the patient of: (a) a medication from said first list of medications currently being taken by the patient and (b) the additional medication proposed to be taken by the patient, and sending the adverse drug reaction warning to the user, in response to determining that the adverse drug reaction warning should be generated, the code generator generating a second code, said second code being different from said first code, said second code representing a second list, said second list including the medications currently being taken by the patient and the additional medication proposed to be taken by the patient, and said second code not disclosing an identification of individual elements of said second list, and the code-output functionality sending said second code to the user.

7. The system according to claim 6 , wherein the code generator is configured to determine whether a code already exists with respect to the first list, and wherein, if so, the code-output functionality is configured to output the already-existing code, and, if not, the code generator is configured to generate the first code and the code-output functionality is configured to output the generated first code.

8. The system according to claim 6 , wherein the code generator is configured to generate the code not responsively to a pharmaceutical characteristic of at least one of the medications currently being taken by the patient.

9. The system according to claim 6 , wherein the drug-input functionality is configured to receive an indication of a dosage of at least one of the medications currently being taken by the patient, wherein the code generator is configured to generate the first code responsively to the list and the dosage, and wherein the adverse drug reaction warning generation functionality is configured to determine whether to generate the adverse drug reaction warning based on the first list, the additional medication, and the dosage.

10. The system according to claim 9 , wherein the code generator is configured to: if the dosage is near a dosage of the one of the medications currently being taken by the patient for which a code has already been generated, generate as the first code the same code that has already been generated, and if the dosage is not near a dosage of the one of the medications currently being taken by the patient for which a code has already been generated, generate as the first code a code different from the code that has already been generated.
